required components are disabled

Hello,

I am trying install AE CS5.5 on my computer:

Windows 7 Professional

srv pck 1

Intel(R) Core(TM) i3 CPU     M 370 @  2.40GHz

Installed memory (RAM):     8.00 GB (7.80 GB usable)

System Type:     64-Bit

Once I get to the actual install portion of the setup is states "required components are disabled" and I am unable to check the box to install. I have 12.8 GB of available space on my computer and the install box indicates that the install will only use 433 MB? Is that correct, seems small. Either way I have plenty of memory, and the box states that I have the 64-bit compatible AE, and it appears I have all the requirements from the back of the box as well. So what gives? Why could it be saying this? Mabe I don't have enough "cache"? Not even really sure what cache is or if it's applicable here but I at this point I'm just taking shots in the dark. Any help would be appreciated. Thank you!!
